Uso de micro inversores em sistemas fotovoltaicos - avaliação comparativa e estudo de caso

Abstract

The growing use of renewable sources in generating systems led to the emergence of new technologies which intend as a goal to realize, using the best possible way, the energy conversion from a renewable primary source in another form of energy, particularly the electrical energy. These technologies are based, fundamentally, in the creation of topologies and circuits that may improve the conversion efficiency. For the photovoltaic systems this concept is focused on the efficiency of the DC to AC converters, which generate electric energy out of the solar energy. Among all the technologies introduced in the market, the rising of the micro inverters brought changes in the design of photovoltaic systems aiming this best possible efficiency. This work has the objective to present a comparative study among the traditional topologies and those which utilize micro inverters, based on energy production in annual terms by means of computational simulations of both systems in specific scenarios.
